Ok so the thought is an armed teacher could respond and stop a shooting after it has begun right? So instead of 17 dead it could have been maybe 12? That’s the price you are willing to pay for your easy gun access? I work in a school, and can assure you that accidents would far outnumber the number of shooting preventions nationwide. This is not the role of teachers, and any teacher dumb enough to agree to carry in a school has no place teaching at all.
